Antioxidants Battle with Free Radicals for Good Health

By Barbara Day, M.S., R.D.

Inflammation is the root of many health problems in our bodies. Inflammation causes heart disease. stroke, some cancers and autoimmune diseases like arthritis. One way to fight inflammation is through your diet.  To fight inflammation through your diet you must eat foods that are high in Vitamins C, Vitamin E, Carotenes and minerals copper, zinc and selenium. These vitamins and minerals serve as compounds called “antioxidants” which can counteract the damage from the ‘free radicals’ which are cell damaging molecules causing inflammation which are formed in response to toxins or natural body processes. Antioxidants protect the body from the effects of free radicals. The antioxidant neutralizes the free radical by giving these free radicals electrons so they can no longer cause inflammation. You could say, antioxidants act as a natural “off” switch for the free radicals.

Keep in mind, not all free radicals are bad. When our immune system needs to attack intruders like viruses, bacteria, our bodies use free radicals to help destroy these intruders.

It’s better to eat the foods that contain antioxidants because you get other nutrients as well rather than just one nutrient if you just take the supplement!
